We report on a search for second generation leptoquarks (LQ) produced in p{ovr p} collisions at {radical} (s) =1.8 TeV using the D0 detector at Fermilab. Second generation leptoquarks are assumed to be produced in pairs and to decay to either {mu} or {nu} and either a strange or a charm quark (q) . Limits are placed on {sigma}(p{ovr p}{r_arrow} LQ{ovr LQ}{r_arrow}{mu}{nu}+jets) as a function of the mass of the leptoquark. For equal branching ratios to {mu}q and {nu}q , second generation scalar leptoquarks with a mass below 160 GeV/c{sup 2} , vector leptoquarks with anomalous minimal vector couplings with a mass below 240 GeV/c{sup 2} , and vector leptoquarks with Yang-Mills couplings with a mass below 290 GeV/c{sup 2} , are excluded at the 95{percent} confidence level. {copyright} {ital 1999} {ital The American Physical Society }
